As of November 30, 2025, the U.S. federal top marginal individual income tax rate remains 37%, the rate set by the Tax Cuts and Jobs Act effective from 2018; it has not been raised to anywhere near the 70–80% range mentioned in the prediction. Various reputable tax references and IRS summaries confirm that 37% is still the top federal bracket through tax year 2025, with current law only scheduling a reversion to pre‑2018 rates (a 39.6% top bracket) in 2026 unless Congress acts, which is still far below 70–80%. However, the prediction’s explicit time window is “within the next decade from 2021,” i.e., roughly by 2031, and that date has not yet arrived. Because the forecast allows until the early 2030s for top marginal rates to reach 70–80%, and we are only in 2025, it is too soon to declare the prediction definitively right or wrong. Therefore, the correct assessment at this time is that the outcome is inconclusive (too early).
